Hi John, This is part of the service one buys upon telling an ISP you want a /24 for multihoming per ARIN NRPM 4.2.3.6. Not a fresh, new or dangerous concept, nor one that fails to work. IIRC, there was an effort to prevent this once... ISPs that wouldn't accept these /24 BGP announcements from their peers. But that collapsed as its enforcers realized it was costing them business and is, today, a historical footnote. Where the block in question is from a legacy registration, what contractual or legal obligation prevents the holder from making a lawful assignment larger than /24, without a multihoming (or any other) requirement? And in perpetuity? Regards, Bill Herrin -- William D. Herrin ................ her...@dirtside.com b...@herrin.us 3005 Crane Dr. ......................
